Be it known that I, JOHN S. CAMPBELL, of Newton, in the county of Sussex; and'State of New Jersey, ha-ve invented n new and useful VImprcwenient iu Check-Rein Hooks or Terre'ts'for Harness sind. I dohereby' s `a. full, clear, and exactude'scription of.n tlie suine, reference being hadto the accompnnying drawngs, making afportion of this speoicntion, i'nvwhichj Figure 1 is e ve'rticnl longitudinal section, representing th h'oo'k of tei-ret 'in-an open condition, to perniit',

the check-rein to be hooked overthe-same'. x

' Figui-e2 is a side 4view of the samenle closed, to prevent the detaehment'of thezeheckfreim Similar letters of refereneeindicate vcorresponding parts in both'gures.

The object of this invention .is to prevent the .heelorein 0fo. harness from becoming ca suellydetnchcd from the hook or'terret over which the saine is hooked-when in'use, nnr1 to thisend the/invention `sonsists in e swingingbaigfcombined with a. plate punctured inthe centre for attachment to theaforesaid hook .or tei-ret, so

th'nt it may be'tnrned forward und downward, toxopen the hook, and allow th'eI'checkreinfto be placed thereon, lund turned backward und' upward in such manner as to close they opening of the.hook, and thus pxevenlz-fthev aforesaid rein from-slipping off. Y v

To enable others to understand the nntuxe and eonstr'ction of my invention, I will proceed to ldescribe with reference to the .dra-wings. i l

A represents thel check-rein hook or terret, which'may be of any appropriate form, and atteched to th'e saddletree, of the harness by thje broed-headedbolt a.' Placed underneath the heed-a of thisbolt is e thin fiat metalplete,.b,.the rearwardly-projecting portionA of which isdivided by two longitudinal slots, so tht'aisliort tongne, c', is formed, which serves as n spring, the purpose of which will b e presently set forth? Those porv tions of the said rear part ofthe plate at each side of this spring ahevehnged or pivoted to thein aber, B,

in such manner that the said bor 'muy lie-"either turned forward' und downward over the head of the bolt a, to open the l1ook,'a s shown in iig. 1, or be `turned upward into u. nearly or quite vertical posi-tion, to' close the opening, at ai, of the said hook, as 'shown in iig. 2,4,the pivotedend of the baxjB being made with two flatl surfaces',

. so .arranged in relation with thcvspringe that the said spring c', noting upon one surface or the other, .will retainr the 'bnr in either its upright op' .depressed position, as the case may be.

When the bar is depressed, as just sot forth, thecheck-r'ein maybe slipped over :nemici-,and as indicated in red outline in tig. Zrwhich being done, the aforesaid bar is tniuedtup to closet-lie opening of the hook, as 'shown in the said iignre, therebyl Reventing all liability oi' the casualV slipping ,or disengagement of the c'heck-1eir\"from the hook. f I

What Ielaim es my invention, and'desire to secure by Letters Patent, i s- Thehinged tongue B, in combination-with the plateb, for attachment toA the check-rein hook, substantially JOHN is.A CAMPBELL.
